To all whom it may concern/ confined in its bearings, and when drawn Be it known that l, WALTER DONALDSON, upon moves dircctly upward in its inclined a citizen of the United States of America, re position, and the inclination-is such that its siding at \\'asliir1gton, Districtof Columbia, upper end clears the burner and other parts have invented certain new and useful Imabove the body.

The draw-bar F is straight and passes lt will be understood that I do not wish to through the elongated inclined bearing f in limit myself to the use of a wick-sleeve; but the lamp-body and inclines inwardly toward this device, as employed herein, is a reprethe wick extending down through the chamsentative one for a connection between the 5o ber c. It has sliding movement, beingclosely sliding parts and the wick. roo

I am aware that prior to my invention Wickraisers have been provided consisting of a draw-bar and wick-sleeve, with a detachable connection between the said bar and sleeve, and that some of these connections are adapted to have sliding movement in order to effect the detachment of the parts; but my invention differs essentially from all such arrangements, as the sliding movement is effected during the operation of raising or lowering the wick and is for the purpose of maintaining the inclined position of the draw-bar in all the varying positions of the wick-sleeve.

I claiml. In combination, the wick-tube, the wick,

4. In combination, the wick-tube, the Wicksleeve, the draw-bar, the sliding connection between said ,bar and sleeve, adapted to permit variation in the relative position of the bar and sleeve in the operation of the parts, and a guide for preventing displacement of the sleeve, substantially as described,

5. In combination, the wick-tube, the wicksleeve, the upwardly -operating draw -bar with the sliding connection to the Wick-sleeve, the outer tube or shell having a chamber for the draw-bar, andaguide projection or tongue on the wick-sleeve extending into said chamber, substantially as described.

In testimony whereof I afx my signature in presence of two witnesses.
